Probably the economy becomes entirely social and cultural. We are already seeing a massive shift toward that anyway with the rise of social media. The new goal of humanity may be a giant collective argument about finding meaning.

Just to note: I don’t think there is an “end game” to any of this. Not really a time where humans are never needed, and not really a point where Ai “learns everything” because I think those are just based on false premises. The more we can make and the faster we can learn, only makes things more complex. So things will expand and possibilities will expand (necessarily) at a rate faster than our capabilities do, because our capabilities themselves expand possibilities.
If that doesn’t make any sense then maybe an analogy:
When all you can do is walk, you only have the land around you to settle. If you have a spaceship that travels the speed of light, then you have a billion star systems to settle with a billion challenges a billion times more difficult than what you’ll find within walking distance. Technology actually *makes the world bigger.* There is no horizon. Everything is infinite.
